PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate user separation and noise estimation of a control channel.SOLUTION: One or more UEs 120 respectively transmit one or more control signals 150, which are multiplexed on a control channel, and a base station 110 receives a control channel signal 150 that includes the one or more control signals. The base station 110, in a single pass, separates the control signals by matching the control channel signal 150 with a base sequence and translating the matched signal to a time-domain representation. In the time-domain representation, each control signal resides at a different tap. The base station 110 identifies taps of the time-domain representation corresponding to an unused cyclic shift or orthogonal cover sequence. The taps are employed to generate a noise and/or interference estimate.SELECTED DRAWING: Figure 1 |
